In the present invention, the arrangement of the feeding mechanism and the detecting box 10, due to the arrangement of the one-way bearing 24, enables the worm 16 to be received by the belt pulley 22 only in one rotation direction, namely, when the sliding plate 4 with a plurality of thermometers is pulled upwards through the threaded rod 7 and the threaded sleeve 8 and the thermometers in the next batch are replaced, the replacement of the detection liquid in the detection box 10 can be completed through the transmission mechanism, and during the second check when the threaded rod 7 and the threaded sleeve 8 pull the slide plate 4 downwards, due to the provision of the one-way bearing 24, no mechanical movement can occur within the feed mechanism, the thermometer to be tested is replaced, the test solution in the test cassette 10 can be replaced at the same time, thereby ensuring the constant temperature of the detection liquid during each detection, further controlling the stability of the constant quantity, so as to avoid the influence on the detection and calibration result caused by the temperature change of the detection liquid which is placed for a long time.

The working principle is as follows: when the thermometer is inserted into the detection cylinder 5, because the diameter difference exists between the cylinder of the thermometer and the vacuole, and the diameter of the vacuole is smaller than that of the cylinder, when the thermometer is inserted into the detection cylinder 5, the vacuole at the lower end of the thermometer can pass through the round hole in the middle of the snap ring 6, and the cylinder cannot pass through the round hole in the middle of the snap ring 6 because of the larger radius, so as to limit the position of the thermometer, after the thermometer and the snap ring 6 are pushed downwards to the lowest end of the detection cylinder, loading is completed, after the thermometers in the detection cylinders 5 are all loaded, the output end of the motor 18 can be started to rotate in the positive direction, at the moment, the output end of the motor 18 drives the worm 16 to rotate, the rotation of the worm 16 is transmitted to the threaded rod 7 through the worm wheel 17, and because of the one-way bearing 24, the belt pulley 22 is in a non-rotating state at the moment, so that the threaded rod 7 drives the threaded sleeve 8 to move downwards, the threaded sleeve 8 drives the sliding plate 4 and the detection cylinder 5 to move downwards along the fixed cylinder 5 until the limiting block 28 moves to the bottommost part of the limiting groove 29 and is in contact with the lower end of the limiting groove 29 and cannot move, at the moment, the vacuole at the lower end of the thermometer just enters the detection liquid below the detection box 10, the depths of the thermometers are the same, and meanwhile, the cover plate 26 enters the fixed cylinder 3 and seals and keeps the fixed cylinder 3 warm;

when the temperature timer needs to be replaced or taken out, the output end of the motor 18 is started to rotate reversely, at the moment, the output end of the motor 18 drives the threaded rod 7 to rotate through the worm 16 and the worm wheel 17, the threaded sleeve 8 drives the sliding plate 4 to move upwards, the cover plate 26 moves to the upper side of the fixed cylinder 3, because the reverse rotation of the worm 16 can be transmitted to the belt pulley 22 through the one-way bearing 24 at the moment, the belt pulley 22 drives the other two belt pulleys 22 and the rotating shaft 13 to rotate through the belt 23, the rotating shaft 13 drives the spiral blades 14 to rotate, and because the rotating directions of the spiral blades 14 at two sides are opposite, the spiral blades 14 at one side draw out the liquid in the detection box 10, and the spiral blades 14 at the other side input the liquid in the water storage box 11 into the detection box 10, so as to complete the replacement of the liquid in the detection box 10, after, the motor 18 can be turned off and the thermometer removed from the test cartridge 5 and replaced.
